OBJECTIVETo discuss feasibility and clinical effects of minimally invasive percutaneous plate osteosynthesis in treating acetabulum anterior column fracture with intact true pelvic brim.

METHODSFrom May 2013 to December 2015, 8 patients with acetabulum anterior column fracture with intact true pelvic brim were reviewed retrospectively. According to Judet-Letournel classification, all were simple unstable acetabulum anterior column fracture. Among them, there were 5 males and 3 females with an average age of 42.8 years old ranging from 22 to 63. The injury was caused by crush in 4 cases, smash of heavy object in 3 cases, and falling down in 1 case. The time from injury to operation was ranged from 5 to 19 days with an average of 9.5 days. Preoperative CT showed high anterior column fracture of acetabulum with intact true pelvic brim, the fracture separation was less than 1 cm. All the patients were treated with closed reduction and minimally invasive percutaneous plate osteosynthesis. The quality of fracture reduction, operation time, blood loss, fracture healing time, hip function and postoperative complications were observed and recorded.

RESULTSAll patients were followed up from 10 to 19 months with an average of 14.5 months. The quality of reduction was classified as anatomical in 4 patients, imperfect in 3, poor in 1 by Matta's score system. The operation time was 30 to 80 min, averaged 51.3 min;the blood loss was 50 to 120 ml, averaged 86.2 ml; fracture healing time was 10 to 19 weeks, averaged 13.3 weeks. At the latest follow-up, the hip function was evaluated by Merle D'Aubigne scoring system, 5 cases got excellent results, 2 cases in good, and 1 case in fair. No vascular nerve injury, wound infection, bleeding, deep vein thrombosis and other complications occurred in 8 patients.

CONCLUSIONSMinimally invasive percutaneous plate osteosynthesis in treating acetabulum anterior column fracture with intact true pelvic brim has advantages of less trauma, less bleeding, quick recovery and good curative effect, and it is a good surgical procedures for acetabulum anterior column fracture.

OBJECTIVETo observe the signal transducers and activator of transcriptions (STATs) protein expression changes and investigate the functional role of STATs pathway in case of high glucose-induced cardiac fibroblasts (CFs) proliferation and collagen deposition in vitro.

METHODSRat cardiac fibroblasts were isolated from 1- to 3-day-old SD rats, cells from the second to fourth passages were used for the experiment. CFs were cultured in Dulbecco's modified Eagle's medium, supplemented with 5.5 mmol/L glucose (NG), 5.5 mmol/L glucose plus 19.4 mmol/L mannose (OC) or 25 mmol/L glucose (HG) in the presence of absence of STAT1 inhibitor (fludarabine, FLU) and STAT3 inhibitor (S3I-201). After 24 h and 48 h culture in vitro, the proliferation of CFs was measured by 3-(4,5-dimethyl-2 thiazoyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. After 12 h and 24 h culture in vitro, the production of type I and III collagen was evaluated using real-time quantitative PCR and ELISA. After 0, 30, 60 and 120 min culture in vitro, the phosphorylated expression of STAT1 and STAT3 was analyzed by Western blot.

RESULTSCFs proliferation was significantly enhanced post 24 h and 48 h HG stimulation, and procollagen I and III mRNA expression was significantly upregulated post 12 h and 24 h HG stimulation. Deposition of collagen I and III was also significantly increased post 24 h and 72 h HG stimulation. STAT1 phosphorylation in CFs was increased after 120 min HG stimulation and STAT3 phosphorylation in CFs was increased post 60 min and 120 min HG stimulation. FLU and S3I-201 could inhibit HG-induced CFs proliferation and suppress of which was stimulated by FLU and S3I-201 could both suppress upregulated procollagen I and III mRNA expression and the deposition of collagen types I and III post HG stimulation. STAT1 phosphorylation inhibition resulted in less mRNA downregulation of procollagen type III than that of procollagen type I post 12 h HG stimulation. The STAT3 phosphorylation inhibition resulted in more significantly upregulated procollagen type III mRNA expression than procollagen type I mRNA expression at 12 h post HG stimulation.

CONCLUSIONHG could enhance the protein expression of phosphorylated STAT1 and STAT3 in CFs, which are responsible for HG-induced increased CFs proliferation and collagen deposition in vitro.

OBJECTIVETo evaluate the left ventricular (LV) radial and longitudinal systolic function in hypertrophic cardiomyopathy (HCM) patients by 3.0 T MR.

METHODSSixteen HCM (HCM group) and twenty normal adults (normal group) were examined with fast imaging employing steady-state (FIESTA) acquisition sequence of cardiac MRI. LV ejection fraction (LVEF), longitudinal shortening (LS) and fractional shortening (FS) in three standard levels were measured to analyze LV radial and longitudinal systolic function.

RESULTSAsymmetric hypertrophy was detected in all HCM patients. The LVEF and FS were significantly higher while LS was significantly lower in HCM group than those in normal group (P < 0.05 or 0.01). FS at basal and middle levels were significantly higher in HCM group than in normal group (both P < 0.01). FS in apex level was similar in the two groups (P = 0.057). Pearson correlation analysis showed that LS was negatively related with the number of hypertrophy segments in HCM patients (r = -0.537, P = 0.032). But there was no correlation between FS and the number of hypertrophy segments as well as FS and LS in HCM patients (r = -0.090, P = 0.739; r = 0.049, P = 0.856).

CONCLUSIONThe LV longitudinal systolic function was reduced but the LV radial systolic function remained unchanged in HCM patients, thus, LS changes could better reflect myocardial systolic function in HCM patients.

OBJECTIVE To analyze the damage range and objective evaluate the vestibular function impairment in patients with sudden deafness at the same time of cochlea damage. To explore the difference of vestibular function damage in patients with sudden deafness with different hearing loss curve types. METHODS Sixty patients with unilateral sudden deafness and vertigo who were hospitalized in our department from August 2016 to August 2018 were selected as experimental group. There were 11 cases of low frequency descending type, 15 cases of flat descending type, 18 cases of high frequency descending type and 16 cases of total deafness type. Sixty healthy volunteer as control group. Two groups of patients underwent caloric test, ocular vestibular evoked myogenic potential(oVEMP), cervical vestibular evoked myogenic potential(cVEMP) and video head impulse test(vHIT). RESULTS The abnormal positive rate of caloric test, oVEMP and cVEMP in the control group was 10.3％, 26.7％, 16.7％ respectively. The abnormal positive rate of caloric test, oVEMP and cVEMP in the experimental group was 68.3％, 60.3％, 43.7％ respectively. The difference between the two groups is statistically significant. The abnormal positive rate of vHIT in the control group was 13.3％. The abnormal positive rate of vHIT in the experimental group was 51.6％. The difference between the two groups is statistically significant. The positive rate of vestibular dysfunction in patients with total deafness and ascending type was higher than that of flat type and descending type, but there was no significant difference between f lat type and descending type. CONCLUSION Patients with sudden deafness may be accompanied by impaired cochlea and vestibular function in different ranges. The vestibular function of patients with sudden deafness can be evaluated effectively by combined caloric test, oVemp, cVEMP and vHIT. The incidence of vestibular dysfunction in patients with total deafness and ascending sudden deafness was higher than that of flat type and descending type. And there was no significant difference in the incidence of vestibular function injury between flat type and descending type patients.

Objective:To preliminarily observe the clinical efficacy of microwave hyperthermia combined with intensity-modulated radiotherapy (IMRT) and chemotherapy for patients with locally advanced gastric cancer.Methods:Forty patients who could not been operated or refused operation were enrolled in this clinical trial, who were confirmed as locally advanced proximal or distal gastric cancer by gastroscopy pathology and imaging. Radiotherapy was delivered by IMRT technology for 5 times per week with a total dose of 46 to 56 Gy (median dose of 50 Gy) in 25 to 28 fractions. Synchronous hyperthermia was given at 42 to 44℃ twice a week, 45 min/time. S-1 or capecitabine-based synchronous chemotherapy was performed, d1-14/3 weeks. The symptom remission rate, adverse reactions, objective remission rate (complete and partial remission) and survival were observed.Results:A total of 40 patients, aged between 56 and 83 years (median age of 71 years), were enrolled in this study. The male-to-female ratio was 7: 1. Among them, 38 cases (95%) showed symptom remission. The most common adverse reactions were grade 1-2 gastrointestinal reactions and leukopenia. The objective remission rate was 87.5%, the 2-year progression-free survival and overall survival rates were 68.6% and 70.5%, respectively.Conclusion:Preliminary findings demonstrate that microwave hyperthermia combined with chemoradiotherapy achieve satisfactory outcomes and yield tolerable toxicity in patients with locally advanced gastric cancer.
